Urban Assault Ride

The Urban Assault Ride originated in Austin June 2003, and since then, its combination of bike race, adventure race, and music concert/festival has taken the country by storm, with 13 cities on this year's itinerary. Teams of two hop on their trusty two-wheelers and navigate the city going from checkpoint to checkpoint (seven, plus two mystery ones) and take on crazy obstacles at each stop, all while racing against the 1,500 or so riders expected to participate. The order in which each team completes these checkpoints is up to them, and they'll want to complete them as quickly as possible for a chance at one of the spectacular prizes. In the spirit of the event, biodiesel is used to fuel the truck which carries supplies from town to town, the start and finish lines are powered by the sun, 95% of the trash left behind is composted or recycled, and proceeds are donated to local nonprofits Austin Ridge Riders and the Yellow Bike Project. See the website for further details and the clue for the first mystery checkpoint, which will be revealed Thursday. The afterparty runs from 10am to 2pm and will feature live music from the Motts (10:30am-noon) as well as tasty vittles, New Belgium beer, a mustache contest, waterslides, minibike limbo, and much more. Sun., June 27, 8am. Fiesta Gardens. $55-65, depending on date of registration. www.urbanassaultride.com.
